Brief History

On January 21, 2017, the Women’s March on NYC coordinated the assembly of an estimated 750,000 people to demonstrate public support for women’s rights. Dozens of unique grassroots organizations joined this event under a shared vision that all humans are equal and deserve equal treatment. We are and have always been 100% independent from Women’s March, Inc.

Following this event, 120,000 individuals registered with Women’s March on NYC to continue receiving information about women’s rights and future events. An additional 33,000 registered to follow Women’s March on NYC on Facebook, Twitter, and Instagram.

Because of this public demand for continued information, education, and events that support human rights, the Women’s March on NYC created the nonprofit Women’s March Alliance (WMA) whose mission is to raise women’s voices through education and activism. We will equip our communities with the tools necessary to demand change and defend our rights.

Our Board

FOUNDER & PRESIDENT Katherine Siemionko has fought for gender equality from inside corporate America for over 15 years. Her use of education and diplomacy to promote collaboration and tolerance awarded her global roles at firms such as JPMorgan Chase & Co. and Goldman Sachs, where she served as Vice President of Business Architecture and Change Management. In 2016, finding herself pushing against an impenetrable glass ceiling, Katherine decided to take the fight against inequality in the workplace public by organizing the 2017 Women’s March on NYC. She subsequently left the private sector and founded Women’s March Alliance, a nonprofit designed to amplify the voice of women through education, empowerment and activism. Katherine is an avid traveler who has road-tripped through almost all 50 states, a poet, writer and animal lover.

TREASURER Julia Coronado is a pioneer woman in the male-dominated world of economics. Less than a third of economics Ph.D.s are women, a share that hasn’t budged over the past twenty years, and the same can be said for female executives at Wall Street firms. Julia, however, is part of that small share. After dedicating five years to obtaining a Ph.D. in economics from the University of Texas, she joined the Federal Reserve Board in Washington, DC before moving to Wall Street. Despite rising to the rank of Chief Economist at multiple large financial firms, she is a witness to the fact that working hard and being good at your job does not resolve many of the workplace disparities and unconscious biasses that prevent women from obtaining equality in the workplace. As a leader in her industry, Julia is determined to use her voice to raise consciousness and empower others to do the same. She believes that through dialogue, organization and action we can move forward toward a more equal world.
